State lawmakers are considering several proposals to improve infrastructure that could hit Missourians' wallets.

One proposal could require residents to pay a higher sales tax in order to pay for transportation projects, and another would let electric utilities seek a surcharge to recoup costs from infrastructure projects.

A third measure would call for issuing several hundred million dollars in bonds to fund improvements on college campuses and state facilities. Taxes that Missourians pay could go to paying off the bonds.

Lawmakers say the influx of ideas comes because there is a new willingness to discuss major challenges facing Missouri. They are skeptical everything would pass in the same year.
